Types

type App

type App struct {
	Requests []Path

	Middlewares Handlers
	Prefix      string
	// contains filtered or unexported fields
}

App is the key struct of the package. App as a member of plugin entity contains the request and the corresponding handler. Prefix is the url prefix and MiddlewareList is for control flow.

func NewApp

func NewApp() *App

func (*App) ANY

func (app *App) ANY(url string, handler ...Handler)

ANY registers a route that matches all the HTTP methods. GET, POST, PUT, HEAD, OPTIONS, DELETE.

func (*App) AppendReqAndResp

func (app *App) AppendReqAndResp(url, method string, handler []Handler)

AppendReqAndResp stores the request info and handle into app. support the route parameter. The route parameter will be recognized as wildcard store into the RegUrl of Path struct. For example:

/user/:id      => /user/(.*)
/user/:id/info => /user/(.*?)/info

The RegUrl will be used to recognize the incoming path and find the handler.

func (*App) DELETE

func (app *App) DELETE(url string, handler ...Handler)

DELETE is a shortcut for app.AppendReqAndResp(url, "delete", handler).

func (app *App) Find(url, method string) []Handler

Find is public helper method for findPath of tree.

func (*App) GET

func (app *App) GET(url string, handler ...Handler)

GET is a shortcut for app.AppendReqAndResp(url, "get", handler).

func (*App) Group

func (app *App) Group(prefix string, middleware ...Handler) *RouterGroup

Group add middlewares and prefix for App.

func (*App) HEAD

func (app *App) HEAD(url string, handler ...Handler)

HEAD is a shortcut for app.AppendReqAndResp(url, "head", handler).

func (*App) OPTIONS

func (app *App) OPTIONS(url string, handler ...Handler)

OPTIONS is a shortcut for app.AppendReqAndResp(url, "options", handler).

func (*App) POST

func (app *App) POST(url string, handler ...Handler)

POST is a shortcut for app.AppendReqAndResp(url, "post", handler).

func (*App) PUT

func (app *App) PUT(url string, handler ...Handler)

PUT is a shortcut for app.AppendReqAndResp(url, "put", handler).

type Context

type Context struct {
	Request   *http.Request
	Response  *http.Response
	UserValue map[string]interface{}
	// contains filtered or unexported fields
}

Context is the simplify version of web framework context. But it is important which will be used in plugins to custom the request and response. And adapter will help to transform the Context to the web framework`s context. It has three attributes. Request and response are belongs to net/http package. UserValue is the custom key-value store of context.

func NewContext

func NewContext(req *http.Request) *Context

NewContext used in adapter which return a Context with request and slice of UserValue and a default Response.

func (*Context) Abort

func (ctx *Context) Abort()

Abort abort the context.

func (*Context) AddHeader

func (ctx *Context) AddHeader(key, value string)

AddHeader adds the key, value pair to the header.

func (*Context) Data

func (ctx *Context) Data(code int, contentType string, data []byte)

Data writes some data into the body stream and updates the HTTP code.

func (*Context) FormValue

func (ctx *Context) FormValue(key string) string

FormValue get the value of request form key.

func (*Context) HTML

func (ctx *Context) HTML(code int, body string)

HTML output html response.

func (*Context) Headers

func (ctx *Context) Headers(key string) string

Headers get the value of request headers key.

func (*Context) JSON

func (ctx *Context) JSON(code int, Body map[string]interface{})

JSON serializes the given struct as JSON into the response body. It also sets the Content-Type as "application/json".

LocalIP return the request client ip.

func (*Context) Method

func (ctx *Context) Method() string

Method return the request method.

func (*Context) Next

func (ctx *Context) Next()

Next should be used only inside middleware.
